This article, through a principal-agent mechanism, constructs a model of the democratic security policy of the Uribe Government, and shows its relationship with the increase in victims of extra-judicial executions called "false positives". The model explains the failures of the democratic security policy by comparing it with an alternative counterfactual policy that involves an optimum level of audit of military units to avoid false positives. It was found that this counterfactual policy could increase the well-being of society.
